    Re: Most reliable 1 terrabyte Hard Drive

    there is no real consensus on this. Some folks like WD and others like Seagate. As others have pointed out though, the quality control on all consumer grade drives is pretty bad. My own experience is that 1 in 4 crap out within 2 months of heavy use, regardless of who makes them...and since by the time they fail, they are in use, replacing them can become non-trivial. That's why my model these days is religiously: SSD as system disk (extremely low failure rates but finite write cycles), and software raid-5 with at least four hard disks for normal storage and volatile systems stuff like /var and swap. Using dual controllers I can get read access speeds of about 3times what a single drive will yield. Of course there is a write penalty but I don't care.

    Re: Most reliable 1 terrabyte Hard Drive

    Hi Bob,
    Yes, to the extraction of data from that drive and transfer of contents to another.

    The only thing left on the inverted drive is a test version of Fedora 28 KDE. But interestingly, since it is installed and refomatted upside down, there has been zero head movement noise, smartctl shows no issues, no bad physical sectors or any out-of-range temperature or seek issues. I am beginning to think that I should invert all the spinner drives in my system to PC board face up. I will internet search to see if there is a difference in drive longevity or performace for inverted devices.

    My 1 terrabyte drives only have RW heads on the top surface of the disk. Installed up-side-down could help protect the surface of the disk if there was an earthquake.

    I ran smartctl -t long /dev/sdb # and after 3 hours, it came back with a clean bill of health. I have the replacement drive all setup. I am just waiting to see how long it will take for the inverted drive to die. It when in inverted on 6 July, following that idea to test it in different positions.
    By the way, it may very well be that there was a piece of dust or debree that caused the initial failure. I am betting/expecting to have more than one year of fault free service with that inverted WD. So, 4 days of use with no clickity clacks

    All my hard drives are mounted vertically. Here is a pic that displays the proper mounting position for a server with lots of hard drives:

    Frankie, like I said before, the WD drives give no warning , they just break suddenly, and you can erase your smile for a few weeks as you try and recover your work.

    Back in the good ol' days of Mainframes, I was helping to manage an IBM 3090 at UCSB, and we had a few of what is called "DASD"ees (Direct Access Storage Device), these were 3 foot diameter disks of 6 or 8 platters running at 6000RPM inside a glass cabinet (with ARGON gas inside), where you could see the foot-long heads moving like crazy over the things. Now, all of these were mounted ON THEIR SIDE, which means, the axle is parallel to the ground, and the disks spin perpendicular to the ground. The logic behind that was that the bearings wear evenly.
    On disks which are spinning horizontally however, they tend to start "wobbling", whereas the top bearing wears our faster than the bottom one, due to coreolis, or just plain gyroscopic effects coupled with vibrations. Then the disks "go bad".

    However, on a more general note, beware of any company which in their name contain the words "federal", "national", "western", "american"... etc. they tend to be the exact opposite of what their name claims (the "federal" reserve being the most shameless perp). Believe you me, I'm an old fox, and I know what I am talking about. EDIT: I remember back in 1995, I went to ACDC ("American" Computers and Digital Components), in Pomona, east L.A., to buy 32GB of RAM, for $32,000, with a cheque LOL. When we got there, the place looked like Fort Knox, even heavier, all chinese dudes with UZIs every 20 feet all around the perimeter of this white building with no windows. Inside, a Chinese top-10 model beauty in ultraminiskirt and high-heels serving us drinks while we waited for the memory sticks. Their parking lot: Mercedes, Ferrari, Lambo, etc......

    the crux of the matter is nobody should be reliant on an HDD regardless of brand or age not to fail and getting upset and stuck with 'a few weeks' of work recovering data when loss occurs. Instead regular backups should be taken to minimise any potential loss of data.

    Re: Most reliable 1 terrabyte Hard Drive

    I have since discovered that the drive problem was due to a corrupted install program that corrupted the very first gpt block on the disk.
    That corruption would throw the driver into a seak/reread loop. My simple solution-- DD to write nulls for a few sectors
    Then format drive as MS-DOS immediately followed by
    Format to gpt.
    Since then, no midnight oil. All is copacetic. Now I have a spare 1 terabyte drive in bubble blister package.

    By the way, my backups are triple done to three different external drives.

    My current passion is participating with the Fedora Docs teams as editor.
    I lost time with the command line tools provided to solve corrupted drives.

    very interesting. But I still would not trust that drive.

    I was a Seagate customer but so many of them died developing problems that I switched to Western Digital, so far they seem more reliable than Seagate.

    The replacement drive in my inventory is a Seagate. I will see where I can donate it. either to the local library or to some local institution needing it
